Thompson's comments follow his UFC 205 draw with Tyron Woodley with the pair expected to re-match and settle the score once and for all.

McGregor could not help but throw his hat in the ring in possibly pursuing a third belt at 170 pounds.

That would mean the two-time champ putting on 15 pounds, a massive jump in weight and one that could prove to bigger a jump.

“To be honest with you, Conor McGregor at 170, I think he’s just going to be thrown around like a little rag doll,” Thompson told Fight Society podcast.

“The weight class is just so much bigger. I didn’t expect Tyron to be as strong as he was. He’s a thick dude, short but thick and very strong opponent.

“He’s definitely going to have to wait. Let’s settle this score first before he even talks about going to 170.”

Should Thompson beat Woodley in the re-match he said he would fight McGregor but stressed a win against a traditionally smaller opponent would do little for his reputation.

“You’re out there to fight the best guys, but it is kind of a lose-lose situation,” he said.

“You go out there and you defeat Conor and everybody will be like ‘you should have beat him.’ What did you think was going to happen?

“But if you lose? So it’s a lose-lose situation to go out there and fight somebody like that.

“Anybody who fights McGregor is going to have a good payday. He’s one of the best guys in the UFC. He’s got two belts."
